IMPROVEMENT IN GRAINING-TOOLS.

Specification forming part of Letters Patent No. 150,198, dated April23, 1874; application filed September 19, 1873A.

To all whom it may concern:

Be it known that I, JOHN N. SMITH, of New York, county and State of NewYork, have invented a certain Improved Method of Graining and Machinetherefor, of which the following is a specification:

The first part of my invention consists of a new method of graining,which, in appearance,'s fully equal to hand-work, and only requires avery short time to do in comparison therewith. This I accomplish bypaint ing, with a varnish or any other compound not affected byoil-paint, on a strip of porous fabric-as silk, muslin, &c.-the designin negative of the wood to be imitated. A piece of cloth coated on oneside with rubber is covered with paint of the color of the grain of thewood to be imitated. The prepared silk or muslin is laid against theplace to be grained, with the painted cloth against it, the rubber sidebeing on the outside. Then, by pressing on the cloth, some of the paintabsorbed by it is forced through all of the parts of the silk which arenot covered with the varnish, onto the prepared surface, so that uponremoving the silk and cloth the graining is accomplished. The preparedsilk may be as long as required, so that any length of graining may bedone without any breaks, and by keeping it in oil when not in use itwill last a long time. Any design such as scrolls, lines, letters, &c.,may be painted in negative 011 the silk and reproduced in any number bythis process in a very short time. It is only necessary to cover 'thecloth with paint occasionally, as it will retain sufficient paint for anumber of impressions. rIhe second part of my invention relates to amachine for carrying the silk and cloth by which the operation may beperformed with facility; and consists of a light iron frame, with ahandle in the center, carrying' two rollers, to which are attached theends of the silk and cloth. The silk, and cloth in going from one rollerto the other, pass over an elastic roller, which presses the paint onthe place to be grained. The three rollers are connected together bycords running over grooved pulleys, so that, as the elastic roller isrevolved by passing passing over the surface operated upon, the otherrollers turn with it, thereby winding the silk and cloth, from one tothe other, keeping' them always taut, but, to describe my invention moreparticularly, I will refer to the accompanying drawings, which are aboutonehalf the size of the machine, forming part of this specification, inwhich- Figure l is a longitudinal section. Fig. 2 is a view of the underside, showing the prepared silk. Fig. 3 is an end view, showing themanner in which the frames are fastened to the handle. Figs. 4 and 5 areviews of a pad used for pressing the silk and cloth into the rounded endof a panel.

a represents the silk or muslin, 81e., and b, the rubber-coated cloth,bothbeing wound around the roller c, and the ends fastened to it by astrip of wood pressing them into a longitudinal groove, c. The roller cruns in the frame fastened to one end of the handle c. The other end ofthe handle c holds the frame f, which carries the elastic roller g nearits end, and the roller h between the handle and elastic roller. All ofthe rollers are parallel, and the silk and cloth pass over the elasticroller g, and are connected to the roller l1J in the same manner as tothe roller c. The elastic roller g is made by binding cotton batting orfelt g1 around a wooden mandrel or shaft, g2, and then covering it witha thin coating of rubber. rIhe grooved pulley g3, with the cord i',causes the roller h to. revolve with the roller g, by the cord t'passing over the grooved pulley h. The roller c is made to turn by thecord j connecting it to the roller h. The frames d and f are secured tothe handle c by two thumb-screws, Z and mf, passing' through slots inboth sides of the frames, so that the sides of the frames may beadjustable to hold different widths of rollers carrying diferent widthsof silk and cloth, as shown at Fig. 3.

Figs. 4 and 5 represent the front and side view of a pad for pressingthe silk and cloth into the top end of a rounded panel, after the erg,operated substantially as hereinbefore set roller g has pressed the silkand cloth as far forth. f

as it `can,Y so that the whole of any shaped 2. The fabric a and clothb, in combination panel may be grained by this machine with* with therollers c, g, and h, and frames d and out any subsequent touching` up,as I make i f,rsubstantial1y as described.

. different-shaped pads for corners, &c. JOHN N. SMITH.

I claim- Witnesses: 1. The fabric a, prepared as described7 in S.CONNOR, combination with the cloth b and pad or roil- ALFRED SHEDLOCK.
